I have generated HTML Webhelp files via Robohelp version 9. However, I want the help to display in a single-pane viewer (with search field, home, print, and foward/back arrows displaying at top in the same pane with the help text) similar to the way online help is displayed in Microsoft Office 2013. Is there an online help viewer that can be coded to call my HTML Webhelp content to display in the single one-pane viewer? If so, how can I implement it?

RH-generated WebHelp will display in your browser; Microsoft uses its own format for their help – you might be able to transform HTML pages into MS’s format, but there’s nothing in RH that will do it for you.

Soo, out of curiosity I opened Word 2010 and summoned the help. It looks like this:

Then I opened the live example at the HelpEssentials site. It opened in my browser and I decided to float it into a window of its own:

So if one uses the free layout that is offered on HelpEssentials, they should be able to come pretty close. Their developer might need to tweak the code a bit to ensure the window opens on its own and sized appropriately with as little chrome as possible.
